# Tesla BMS_a067 / BMS_a068: Battery Performance Limited

By the EV Fix Guide editorial team · Updated October 24, 2026 · [How we estimate costs](https://evfixguide.com/about#how-we-estimate-costs)

## Quick answer

BMS_a067 and BMS_a068 mean the car has found a problem inside the high-voltage battery that limits its performance. Range and charging speed drop, and with BMS_a068 acceleration and top speed are reduced too. The car is OK to drive, but Tesla says service is needed to restore full performance. At a Tesla Service Center this typically costs **$0 (Under battery warranty) / $12,000 - $20,000 (Pack replacement, out of warranty)**. An independent shop charges about **$2,500 - $7,000 (Module-level repair, where available)** — potential savings of **50% - 80% (out of warranty)**. **Do not attempt this at home.**

## Symptoms

- 'High voltage battery performance limited - OK to drive - Schedule service soon' alert (BMS_a067)
- 'High voltage battery requires service - Acceleration and charging performance reduced' alert (BMS_a068)
- Lower maximum range and slower charging than before
- With BMS_a068: weaker acceleration and lower top speed

## Repair cost: Tesla vs independent shop vs DIY

| Option | Typical cost (USD) |
| --- | --- |
| Tesla Service Center | $0 (Under battery warranty) / $12,000 - $20,000 (Pack replacement, out of warranty) |
| Independent shop | $2,500 - $7,000 (Module-level repair, where available) |
| DIY | Not possible at home (High-voltage hazard) |
| Potential savings | 50% - 80% (out of warranty) |

Ranges are US estimates compiled from owner reports and shop quotes; prices vary by region, model year and parts availability. Report your price.

## Can an independent shop fix it?

Inside the 8-year battery warranty, this is a Tesla warranty job. Out of warranty, a few independent EV battery labs can diagnose the pack and replace a faulty module or component instead of the whole pack.

## How professionals repair it

**Safety warning:** The fault is inside the high-voltage pack, so there is no safe owner repair. Follow Tesla's interim advice: keep the charge above 30% so the range estimate stays accurate, and book service.

### Tools a shop uses

- Tesla app and screenshots of the alert
- Purchase date and odometer reading (for warranty)

### Steps

1. Keep driving normally; Tesla says the car is OK to drive.
2. Keep the battery above 30% while the alert is active. Tesla warns the displayed range may not match the real charge level below that.
3. Screenshot the alert and note your current maximum range at 100% (or at your usual charge limit) so you can show the change.
4. Check warranty coverage: 8 years with a mileage limit that depends on model and year.
5. Book service promptly. Tesla warns that without service, range, charging speed and power can keep getting worse.
6. Out of warranty, get a diagnosis and quote from an independent EV battery specialist before agreeing to a full pack replacement.

**Pro tip:** Do not try to 'recalibrate' the battery with repeated full charges and deep discharges when this alert is active. The problem is a detected internal fault, not a range estimate that needs adjusting.
